Trial summary

Ultrasound-guided Modified Thoracoabdominal Nerve Plane Block (M-TAPA) is performed deep into the costochondral aspect at the 9th-10th costal level by injecting local anesthetics deep into the chondrium. It provides blockage of both the anterior and lateral cutaneous branches of the thoracoabdominal nerve. Read more about this study

About this study

Official title: Ultrasonography-Guided Bilateral Modified Thoracoabdominal Nerve Plane Block With Perichondrial Approach (M-TAPA) For Postoperative Pain Management In Living Liver Donors: Randomized Controlled Study.

Ultrasound-guided Modified Thoracoabdominal Nerve Plane Block (M-TAPA) is performed deep into the costochondral aspect at the 9th-10th costal level by injecting local anesthetics deep into the chondrium. It provides blockage of both the anterior and lateral cutaneous branches of the thoracoabdominal nerve. As there are studies showing M-TAPA block to be effective for postoperative analgesia for other abdominal surgeries, its effect on patients undergoing living liver donor surgery has not been studied yet. We hypothesize that M-TAPA block performed in living liver donors would reduce opioid consumption in the first 48 hours after surgery.

Read the detailed description

Open hepatic resection for living liver transplantation donor surgery can cause severe postoperative pain and if not treated properly, may increase the risk of chronic pain development, which has a significant impact on the patient's daily life quality. The use of interfascial plane blocks for pain control has increased in recent years, as ultrasonography (USG) has become a part of daily routine. Interfascial plane blocks provide effective postoperative analgesia. Additionally, reducing postoperative opioid consumption may be a useful strategy to provide hemodynamic stability and promote early mobilization. Case reports state interfascial plane blocks to be effective and safe for providing effective analgesia compared to systemic analgesia in living liver donor surgeries. As studies are showing M-TAPA block to be effective for postoperative analgesia for other abdominal surgeries, its effect on patients undergoing living liver donor surgery has not been studied yet. We hypothesize that the M-TAPA block performed in living liver donors would reduce opioid consumption in the first 48 hours after surgery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • M-TAPA plane blockProcedure or surgery

    As the patient is in the supine position, the high-frequency linear US probe (11-12 MHz, Vivid Q) and a 22-G 80-mm needle (Pajunk Sonoplex Nanoline Stim Cannula, Germany) will be placed in a sagittal position at the costochondral junction at the level of the 9th and 10th ribs. After the rib and the external oblique, internal oblique, and transversus abdominis muscles are visualized on USG, using an in-plane technique, the block needle will be advanced and the block location will be confirmed by injecting 5 ml of saline between the internal oblique and transversus abdominis muscles. Once the block location is confirmed, 30 ml of 0.25% bupivacaine (Buvicaine ®) will be applied bilaterally (60 ml in total).

  • Postoperative pain managementProcedure or surgery

    For preemptive analgesia, morphine (Morfin ®) 0.05mg/kg and Ibuprofen 400mg IV (Ibuprofen®) will be administered to all patients before the surgical incision. An additional dose of ibuprofen 400mg IV, meperidine (Aldolan ®), and tramadol (Contramal®) 1mg/kg IV will be administered to all patients 30 minutes before wound closure.10 mcg/ml fentanyl containing PCA will be connected to all patients without infusion and boluses 0,35 mcg/kg,15-minute lockout period, maximum 100 mcg per hour. Postoperative patient evaluation will be performed by another anesthesiologist. If the NRS score is ≥ 4, 0.5 mg/kg IV meperidine (Aldolan®)will be administered as a rescue analgesic.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Opioid consumption (Fentanyl PCA)

    The primary aim is to compare postoperative opioid consumption from the PCA device.

    Measured: Changes from baseline opioid consumption at postoperative 1, 2, 4, 8, 16, 24 and 48 hours

Secondary outcomes (3)
  1. Pain scores (Numerical rating scale-NRS

    The secondary aim is to compare NRS at the postoperative 48 h. Postoperative pain assessment will be performed using the NRS (0 = no pain, 10 = the most severe pain felt). The NRS scores will be recorded.

    Measured: Changes from baseline pain scores at postoperative 1, 2, 4, 8, 16, 24 and 48 hours]

  2. Need for rescue analgesia (meperidine)

    The secondary aim is to compare rescue analgesia used in the postoperative 48 h.

    Measured: Postoperative 48 hours period

  3. Adverse events

    The secondary aim is to compare the adverse events (nausea, vomiting, itching) related to opioid use.

    Measured: Postoperative 48 hours period
